I am a 10 year old developer and i am going through the process of publishing my app to the app store....

I have made an app with the corona sdk, i have downloaded Application Loader to submit my compressed .app file, but when i am sending to itunes i get an error saying:

1) Apple's Web Service was not successful

2) Unable to authenticate the package: 788299253.itmsp
